SPECIFICATION forming part of Letters Patent No. 422,961, dated March 11, 1890.

Application filed September 25, 1889i Serial No. 324.990. (No model.)

T @ZZ whom t may' concern: l

Be it known that'l, JAMES ARTHUR Mon- RISON, a citizen of the United States, residing at Spencer, in the county of Worcester and State of Massachusetts, have invented a new and useful Flushing-Tank, of which the following is a specification.

This invention relates to flushing-tanks,

i and it has for its object to provide a device of this class in which an overflow shall be dispensed with, surplus water accumulating in consequence of a leaky inlet being allowed to escape through the flushing-valve operated by a iioat.

A further object of the invention is to so construct a device as to regulate the quantity of water discharged at each flush, the same quantity of water being allowed to es cape each time the iiushing-valve is operated.

W'ith these ends in view the invention consists in the improved construction, arrangement, and combination of parts which will be hereinafter fully described, and particularly pointed out in the claims..

In the drawings hereto annexed, Figure l is a perspective view, one side of the flushing-tank having been broken away for the purpose of showing the construction more clearly. Fig. 2 is a vertical sectional view.

Like numerals of reference indicate like parts in both figures.

l designates the Bushing-tank, which is of ordinary construction and provided with the escape-pipe 2, the upper end of, which forms a seat for theushingvalve 3, which may consist of an ordinary relastic disk having a downwardlyextending stem e, forming a guide and attached to the under side of a cap 6, the upper end of which has an eye 7 for the attachment of an operating-chain 8L 9 designates a cap, which is screwed upon the upper end of the escape-pipe 2, and to which is secured a valve-cage 10, having an upwardly-extending guide-tube ll, through which the chain S extends. Mounted upon the tube 11 is a spherical or other suitablyshaped loat12, having a centralvertical tube 13 to enable it to slide upon the guide-tube 11.

To the chain Sis attached a ring or stop 14 at a point directly, above the upper end of the guide-tube 1l, where it shall not interfere with the perfect closing of the valve 3. When the float 12 rises upon the guide-tube 11 and reaches the upper end of said tube, it will engage the stop 14E, and thus raise the valve 3 from its seat and cause a portion of the contents of the tank to escape.

To an upright 15, mounted upon the upper edge of the tank, are pivoted two levers 16 and 17. The upper lever 16 has its inner end connected with the operating-chain 8, and it is provided at its outer end with an operating-cord 1S. The lever 17 has its inner end connected by a chain 19 with the iioat 12, and the outer end of said lever 17 is provided with a counter-weight 20. is provided on its under side with a segmental toothed bracket 21,- which is concentric with its fulcrum, and which is adapted to be engaged by a toothed arm or catch 22, extending upwardly from the lever 17.

In operation the admission of water into the tank may be regulated by means of the float l2 in the well-known manner. Vhen the iioat rises to a point at which it engages the stop 14E upon the chain S, it lifts the flushingvalve, and the surplus water escapes. lVhen for the purpose oi' iiushing the tank the lever 16 is operated, the toothed arm or catch 22 will engage the toothed segment 21 of the lever 16, and the latter will thus be retained, holding the flushing-valve in a raised position until the float 12 sinks to a point at which the chain 1S), connecting it with lever 17, is stretched. The inner end of lever 17 will then be depressed, throwing the toothed arm or pawl 22 out of engagement with the toothed segment 2l, and the ilushing-valve will then be allowed to descend and close the outlet. Y

lt will be seen from the foregoing that the duration of the flush may be regulated by regulating the length of the chain 19 and the point at which the stop 14 is adjusted upon the chain S.

The general construction of the device is simple and inexpensive, and it is not liable to get out of order.

Having thus described inyinvention, what I claim, and desire to secure by Letters lPatent of the United States, is?-h 1. The combination of the [iushing-tank, the escape-pipe, the valve, the valve-cage having the upwardly-extending guidetube, the

The operating-lever 16 l'OO operating-ehain extending from the Valve of the escapepipe, the valve, the valve-Cage having an upwardly-extending guide-tube, the operating-chain eXtendin g from the valve through said tube and havinga stop, and a fioat having a vertical tube, whereby it is mounted to slide vertically upon the said guide-tube, substantiallyas and for the purpose Setforth.

3. The combination, With the flushing-tank, of the escape-tube, the valve seated upon the latter, an operating-lever vhaving its inner'. end connected by a chain with said valve, and provided With a toothed segnient'adaptedfto r be engaged by yaf'toothed iarm or catch fextending from a Weightedlever, Substantially `j i I 17, andthe guide-tube ll,inolosin'gthe chain 4f; The eo1nbination,'withthe iushingtank, ofth'ee'soapetube, the valve eatedupon-tlhe as and for thepurpo'se set forth.
